Agree, if you will take in account I am not professional technician, but amateur. Having no space on my table ( two monitors, , two keyboards, audio speakers) I have found that it is possible to organize my equipment in stack. I have purchase framing shelve (stack) from furniture shop, recombined the height of the shelves in rack according to the height of the units, made power communication - one power cord is going from the stack. The stack can be easily moved across the room, taking the most convenient position (wheels) near the my working table. The only stereomicroscope has the temporary place on the desk, when i am repairing motherboards. I am sharing this idea among the members.
